small multiple-member electoral district
A type of electoral district used in Japan, electing a small number of representatives (typically 2–6) under the single non-transferable vote system. Contrasts with 小選挙区 (single-member district) and 大選挙区 (large multi-member district).
The medium-sized electoral district system was once used in Japanese House of Representatives elections.
In a medium-sized electoral district, voters cast a ballot for a single candidate.
